Solution Overview

Problem

Current surgical devices are unable to perform purse-string suturing laparoscopically and cannot integrate tissue resection, stapling, and purse-string suture forming functions in a minimally invasive manner, particularly when access is restricted through a trocar cannula.

Innovation Solution

A surgical device with a clamp, staple anvil, and stapling unit, equipped with purse-string suture needles and an anchor attachment assembly, allowing for simultaneous tubular tissue resection, stapling, and purse-string suture formation, suitable for use in minimally invasive procedures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If current surgical staplers are used to perform tissue resection and stapling, then cutting and stapling functions are achieved, but purse-string suture forming capability is lost

Engineering Contradiction:

Improvesuture forming capabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple surgical functions (purse-string suture forming, tissue stapling, and resection) into a single integrated device. The clamp assembly includes both a purse-string suture profile with needle delivery mechanism and a stapling unit with anvil and cartridge, allowing sequential performance of suture formation, stapling, and cutting without requiring separate devices.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surgical device is designed as a multi-functional instrument that can perform diverse surgical tasks through a single device. The clamp assembly can form purse-string sutures using the suture profile and needle, apply staples using the stapling unit, and perform tissue resection using the blade, making it a universal tool for complex anastomosis procedures.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If current purse-string suture devices are used in open surgery, then purse-string sutures can be formed, but minimally invasive laparoscopic access is not achieved

Engineering Contradiction:

Improveminimally invasive accessVSAvoiddevice configuration

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The purse-string suture needle and anchor assembly are nested within the hollow interior of the shaft. The needle can be advanced through the shaft to deliver anchors through the tissue, allowing the suture forming mechanism to be contained within a minimally invasive laparoscopic instrument that can pass through a trocar cannula.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The device is segmented into distinct functional modules: the shaft for minimally invasive access, the clamp assembly with separate purse-string suture profile and stapling unit, and the blade assembly for resection. This segmentation allows each component to be optimized for its specific function while maintaining overall compatibility with laparoscopic access.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If laparoscopic instruments with restrained access through trocar cannula are used, then minimally invasive surgery is achieved, but purse-string suture formation capability is lost

Engineering Contradiction:

Improvepurse-string suture capabilityVSAvoidinstrument access length

Core Design Contradiction:

Adaptability or versatilityVSLength of moving object

Solution Approach 1:

The purse-string suture needle is housed within the shaft's hollow interior, allowing it to be delivered through the limited access provided by the trocar cannula. The needle can be advanced along the longitudinal axis of the shaft to reach the surgical site and deliver anchors for suture formation, maintaining minimally invasive access while enabling complex suture capability.

Inventive Principle:

Principle #7Nested doll (Nesting)

4Productivity

If multiple separate devices are used to perform resection, stapling, and suture formation, then each function can be performed, but surgical time and procedural complexity increase

Engineering Contradiction:

Improvesurgical efficiencyVSAvoidnumber of devices

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent merges resection, stapling, and purse-string suture formation functions into a single integrated clamp assembly. The device includes a blade for resection, a stapling unit with anvil and cartridge for stapling, and a purse-string suture profile with needle delivery mechanism for suture formation, all contained within one instrument that can be used sequentially to complete complex anastomosis procedures.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The surgical device is designed as a universal instrument capable of performing multiple surgical functions through a single device. The clamp assembly can form purse-string sutures, apply staples, and perform tissue resection, eliminating the need for multiple separate devices and reducing surgical time and procedural complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
